Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

CLS55 8-cyl

Reference PE12001 & EA13003 after filling up I smelled a strong gasoline odor in the car. Upon further inspection, the odor was coming from the rear of the car. It smelled like the drivers side rear seat cushion had been soaked in gasoline. The odor was so strong, driving the car with the windows up was impossible. I did some research online and found out that this was a common problem with the Mercedes amg cars. As instructed online, I removed the seat cushion opened an access panel and could see liquid gasoline pooling on top of the fuel level sender unit. I could also see where the unit had cracked, allowing gas to escape the tank. I contacted mbusa about this problem and they advised me to see the dealer. As expected, the dealer diagnosed it as a faulty fuel sender unit. They contacted Mercedes on my behalf to attempt to get assistance with this repair. Mercedes denied all assistance under the standard and emissions warranty leaving me with over $1000 in repairs. In 2009, my car was previously repaired under recall #2008-020001 which was supposed to fix this problem, but it clearly failed to fix the problem permanently. I had to get my car repaired by a third party repair shop and feel disgusted by the Mercedes inability to fix such a faulty and serious design flaw. They would rather make their customers pay $1000-2000 to avoid passing out from gasoline fumes or risk being killed in an explosion from a collision.

CLS55 6-cyl

  • Automatic transmission
  • 5,100 miles
: the contact stated the vehicle had serious transmission problems. The vehicle lurched continuously while driving at 10 mph. There was also a loud clunking noise when the vehicle shifted gears. The vehicle was taken to a service dealer, who determined there was a problem with the fuel pump. The fuel pump was replaced, but the problems continued. The vehicle was then taken back to the service dealer, who was unable to duplicate the issue.
